9 To all whom t may conce/Mt.

Be it known that We, VVILLLAM il'. Hon. LM-msn, iusnnsion lV. HOLLANDER, and ll-us Hohenstein, citizens ot the United States, re 'siding et Port Arthur? in the countyo'f Jet'- erson and State of Texas, have invented cerain end useful improvements in intilsre Headlights, o which the following is s speeiticetion, l

This invention relates to improvements in anti-glare headlights.

The primary ,object of this invention is the provision of a lamp, such as is ordinarily use for a heed light upon automotive vehicles, embodying improved means whereby the light rays therefrom may be controlled oli so thut the same will emanate therefrom in anti-glare manner.

il 'further objecty of this invention is the provision of un enti-glare headlight for general use, such as upon automotive vehicles, by ineens ot which light. rays niety he adjust ed as to their enianation from the headlights, so that: the saine will he directed downwardly, or in any other direction desired, so that the saine will not glare directly into the vision of approaching traiic.

further object of this invention is the provision' of a novel means associated with sin anti-glare headlight for control of light ther objects and advantages oi' this invention will he apparent during the course of the following detailed description.

.ln the aeooinpauyingg drawings, forming e part. of this specification, and wherein siinila' referente characters designate corresponding ports throughout the several views:

Figure l is a front elevation of the ini4 proved headlight..

Figure 3 is an inside rien7 of a retaining,` oop associated. with the headlight.

lligure el is a front view of an inner the headlight showingn the essential as of the l'ght controlling; ineens as l eiierehy. ire 5 is a rear vienv of the details 'tinted in Figure 4i.

Figure is a 'fragmentary View, partly illusview, showing cooperating details of the 60 housing;l of the improved headlight. ln the drawing, wherein :t'or`the purpose ont illustration is shown out the preferred einlaodiinent ot this invention, the letter may generally designate the headlight7 which may 65 include a housing construction B; and mea is C tor controlling the light rays in so fat as their passage from the housing B is oncornell.

Referring to the housing ll, the saine pret- 70 erahly includes the outer cylindrical shaped casing; lll1 which is entirely open 'forwardly thereof` and at its rear end is provided with a closure tl which may he retained upon the hotly l2 oi the casingl l0, as by means ot' u 75 retaining ring lil. Forwardly of the outer casing. the saine is preferably outwardly flanged, as at l5, in annular manner, said flange being polygonal shaped in cross tion, and preferably having a pair of oppo- S0 sitcly positioned grooves or recesses 17 extending tansversely through the crimped flanged portion 15, which receive certain retaining,l springs 18 ot a retaining cap 2O associated with the casing l0, as will he subse 85 quently described. c

The housing B also preferably includes an inner casing 25, preferably of cylindrical shell formation, which may he entirely open at its rear end, and at its torirard end is 9o provided with nn outwardly extending annular flange 2-,y adapted when the cylindrical shell 25 is slipped within they outer casing4 lt) to be positioned over the forward fece 2&5 Yof the annular flange portion ot' said hous 95 ing or casing l0.

llpon the inner or rear surface of the flange 2o, it is preferred to provide pins 30, extending rearwardly from the plane ofthe flange 26, which may engage through suitable 100 openings-3l in the forward face portion 28 ot/ the flange l,so that the inner shell muy always have e dclinite position relative to the outer casing" itl. Transverse grooves 33 are diametricul y opposed and transversely prolos lul in the Hangs 26, which when the shell assembled within the easing l0, align with the transverse openings 17 in the flange l5 the casing l0. lo-wed springs 35 are preztershly provided nikon the inner surice lio of the flange 26, for abutment against, the flange face 28, so that there will be no liability of collapsing of parts ot the housing B when assembled as hereinafter to be described. The attachingr cap 2l) is preferably ot' ringl shaped formation, including,r the front flange 35, and the annular flange no. The annular flange 36 is, of course, ot suflicient diameter to just Fit, over the crimped portion 15 ot' the casing 1), and as a retaining feature, the same 1s provided with the retaining sprinqs 18 upon the inner periphery oi' said annular flange 36, which springs are connected at their inner ends adjacent the. front iangc and are outwardly rolled upon their tree ends so that when said retainingr springs are slid throufrh the aligning recessesii andY 17 said rol ed portions will rest against the rear surface 40 of the annular liange portion 15, and thus prevent any accidental detachment of the retaining cap or ring 2() with respect to the other housing details. It is preferred to provide a transparent plate 42, preferably ot' disc f formation, for support upon the front flange 35 ot the. retaining member 20, as by supporting' brackets 43. Packing may he provided ior maintaining this plate in posi tion so that the saine may he clamped in nonbrealcible position intermediate the front flange 35 and the shell flan e 2G.

Referringr to the means for controllin light rays so that the saine may pass through the glass front l2, in anti-glare manner, the

inner .shell 25 may appropriately be included as a part thereof, since the details ot' the means C are mainly supported therehy. A segmental concave-convex reflector 51') is forwardly mounted in the inner'shell 35, so that the concaved` reflecting surface 5i thereof faces tothe rear. lt is preferred that 'they reiector 50 he bolted or otherwise secured, at 52, to the top of the shell 25, so that the refieotor depends interiorly of said shell 25 as above outlined. 55, adapted to detachably receive a hulh, is reciprocahly carried substantially centrally o' the reiiector 50, through an opening provided hy an annular' flange 516 of said reflector, so that the bulb 56 fits within the pocket prol'idcd by the reflector 50, Where h v rays oi light may reflect from the concaved surface 51, as will be subsequently deacribeiil. A second reflector (i0, of any ap- .iroved type, although preferably a mirror, 1s hingedlv supported,'as at (il, at the lower cnil of a ange 62a which depends from the top of the shell Q5. The rays of light from the bulb 56. directly, as well as by deflection .rom the reflector 50, will strike the mirror anrface olf the reflector 60 for dedection therefrom forwardly through the transparent disc So that the rays of light emanating from the headlight may elevated or lowered A socket.

as desired, a tubular member 62 is adjust lably carried within the housing B, being horizontally supported therein at the top thereof. iht the. forwardfend, the tube 62 extends through an opening 63 in the front re-lector 50. At the rear end it is proton ably screw' threaded, as at 64; slidahly extending through an opening' 65 in the rear end 1l of the outer casing 10. Inner and outer clamping nuts 66 and 67 are preterahly provided upon the screw threaded por` tion 64, whereby the tube 62 may be maintained in a desired position with respect to the housing l. A nut is adjustalrly positioned upon the screw threaded end 64, wit-hin the housing B, providing oppositely extending pin portions 71 'pivotally and,

slidably receiving the bifurcated end'72 ofV an arm 73, which depends within the housing ll at the rear end thereof, and is rigidly connected to the rear et' the inner relier-tor 60. lt is obvious that upon rotation of the tube 62 within the housin B, the nut 7l) may he fed alon the said tu G2, incident to its screw tireaded engagement therewith, whereby the plane of the recctor. G() may be inclined to eieet the passage of rays from the housing' A vpin or shaft 80 is rotatably carried within the tube 62, with its rearend extend ing; from the screw threaded portion 64 of said tube and providing a screw head 8l thereon. The shaft 8O extends entirely through the tube. and at the forward end -ot the tube extends therefrom and provides `a screw threaded portion 83,. Lock nuts 84 are provided upon the screw threaded' portion 84 adapted for abutment against the forward end of the tube 62 to define af proper position' of the shaft 80 within the' tube 62 against longitudinal movement with. respect thereto. A nnt- S5 is adjustahly carried by the screw threaded portion. 83 of the shaft 80 having oppositely extending pin extensions thi hereon which pivotally receive n hifurcated end S7 of a rocher erin SS, which pivoted, as at 39, at its lower end, to a hraclrei 9H rigid iwith the orwerd reflector 50. Intermediate 'its ends, the rocker member 88 is enlarged, providing an opening 92 for receiving the reciprocable socket 55, having a in and slot connection 9:5 therewith,I .where y upon rocking' movement of the arm 88, the socket 55 may he slid rearwardly or forwardly within the ren Hector 50.

At the lowerl rear end olf the housing' E,

it is referred to rovide a socket 95 which P P i may exteriorly.r and inl'eriorly of the lions ing l), have electric connectors or plugs Sie 'and'Ql "A cable EN extends from the plug 97 within the housing B, rearwardly and upwardly thereideng for electrical connee tion with the reciprocable socket "I with which the hull 56 is in electrical connect lil@ gauging"l ravs .mugace im sup *ung a mai; for
